VX-050DA
The VX-050DA is an Digital power amplifier used for the VX-3000 systems which is compliant with the European Standard EN54 for fire alarm systems.It is a module type with 1 channel of class-D digital power amplifier, which contribute to energy-saving and light weight design. The VX-050DA also features standby mode to be set for reducing standby power consumption. It requires a dedicated control units VX-3004F, VX-3008F, VX-3016F and power supply unit VX-3000DS.
